This data set contains details of 4 PWR rods irradiated in EDF commercial reactors. Two of the rods were re-fabricated and ramp tested in the CEA OSIRIS reactor to investigate their PCI resistance. The data set contains details of the pre-characterization of the fuel pellets, the cladding tube and the assembled fuel rod. The following is an outline of each fuel rod and the data available.

Rod G07: This is rod FF06E2BV/G07/1067 irradiated for 3 cycles in the EDF Gravline 3 PWR to a final discharge burn-up of 34.783 MWd/kgU. The average powers in the 3 cycles were approximately 17, 24 and 21 kW/m. The final fission gas release was measured as 0.49 %. Data available from this rod include:

Rod H09: This is rod FF0EFELX/H09/5007 irradiated for 4 cycles in the EDF Cruas 2 PWR to a final discharge burn-up of 46.060 MWd/kgU. The average powers in the 4 cycles were approximately 22, 20, 18 and 15 kW/m. The final fission gas release was measured as 0.8 %. Data available from this rod include:

Rod J12: This is rod FF0LCMJV/J12/5105 irradiated for 2 cycles in the EDF Gravline 5 PWR to a final discharge burn-up of 23.852 MWd/kgU. The average powers in the 2 cycles were approximately 16 and 23 kW/m.

A section of this rod was cut from span 5 between grids and ramp tested as J12-5 in the CEA OSIRIS reactor. After conditioning at 21 kW/m it was quickly ramped and held at 39.5 kW/m and discharged without failure. The final fission gas release after ramping was measured as 0.74 %. Data available from this rod include:
Fission gas release including isotopic composition of released Kr and Xe.
Metallography at 2 locations.

Rod K11: This is rod FF06E2BV/K11/1090 irradiated for 2 cycles in the EDF Gravline 3 PWR to a final discharge burn-up of 25.437 MWd/kgU. The average powers in the 2 cycles were approximately 21 and 23 kW/m. The final fission gas release was measured as 0.2 %. Data available from this rod include:

A section of this rod was cut from span 5 between grids and ramp tested as K11-5 in the CEA OSIRIS reactor. After conditioning at 24 kW/m it was quickly ramped and held at 43.7 kW/m and discharged without failure. The final fission gas release after ramping was measured as 6.3 %. Data available from this rod include:

Diameter measurements along the length of K11-5 before and after ramp.
Fission gas release including isotopic composition of released Kr and Xe.
Metallography at 4 locations showing evidence of dimple filling.
